Exhibit 3/A STRESS TABLES STRESSES In the following tables, we have applied various stresses to our Base Case. There are two types of stress that we use: - A REDUCTION IN LEASE RENTALS: in our Base Case, net stress-related costs result in a 4.5% reduction in lease rentals. In the tables, as a stress to our Base Case, we have applied a further change in lease rentals, by the percentages shown. We have used this change in addition to the 4.5% Base Case reduction, and kept the other assumptions constant, as a proxy for the change in the amount of net cash available to repay principal that would result in any circumstances where there was any combination of (1) an increase or reduction in lease rentals, (2) an increase or reduction in net stress-related costs, (3) an increase or reduction in aircraft operating expenses, (4) an increase or reduction in SG&A and (5) an increase or reduction in interest costs, including swap costs. - A DECLINE IN PORTFOLIO VALUE: in our Base Case, we assume that aircraft values decline over time in accordance with the depreciation curve that is used to determine the Assumed Portfolio Value under our indenture. In the tables, as a stress to our Base Case, we have set the Adjusted Portfolio Value, at a specified percentage of the Assumed Portfolio Value under our Base Case. You should refer to MSAF's prospectus dated November 4, 1998 under "Description of the Notes -- Payment of Principal and Interest -- Principal Amortization" for a description of the depreciation curve and how the Assumed Portfolio Value and the Adjusted Portfolio Value are determined. We have used this reduction in portfolio value to illustrate the effects of a decline in the value of our aircraft that is greater than what the Base Case assumes. EFFECT OF A PERMANENT CHANGE IN LEASE RENTALS In preparing the tables below, we have started with our Base Case and have varied lease rentals, by the indicated percentages, beginning in years 3 and 6. If our lease rentals were to vary as shown below and all of the other assumptions were to prove correct, then the expected maturities and weighted average lives of the respective subclasses of 1998 Notes would be as shown below. Statements of yields for a particular subclass of notes in these tables are based on the assumption that the purchase price for such notes is 100% of the face value.

Payment of this increased amount may shorten the weighted average lives of the class A notes and lengthen the weighted average lives of the subclasses of notes that rank behind the class A notes in priority of payment. The following tables show the expected maturity and weighted average life of each subclass of 1998 Notes if the Adjusted Portfolio Value permanently declined to a given percentage of the Assumed Portfolio Value, beginning in years 1 and 5.

We would be negatively affected by a decline in the demand for aircraft. We have assumed that such a decline in demand or "RECESSION" will result in a decline in aircraft values, as well as an increase in defaults and downtime and a decline in operating lease rental rates. We have prepared the following tables to show the effect on expected maturities and weighted average lives of the subclass B-1, C-1 and D-1 notes if recessions of different lengths were to occur in the future. In preparing the following tables we have assumed that a recession would have the following effect on MSAF group: - Aircraft values would fall on the first day of the recession to a given percentage of the Assumed Portfolio Value under the Base Case. This decrease would trigger an increase in Scheduled Principal Payment Amounts on the class A notes being paid if amounts were available. - After a period of two years following the first day of the recession, we have reduced lease rentals by a given percentage as a proxy for a combination of the reduction in lease rentals and the increase in net stress-related costs that we assume would occur as aircraft were re-leased or lessees defaulted. This would result in less cash flow being available to make payments of interest and principal on the 1998 Notes. - The recession would last a given period of time. Afterwards, the Adjusted Portfolio Value would return to the Assumed Portfolio Value under the Base Case on the first day after the recession. Two years after the end of the recession, lease rentals would return to the Base Case. Actual experience will likely differ from the assumptions we have used in preparing the following tables. Specifically, we can give no assurance that periods of weak traffic growth and lower demand for aircraft will be followed by periods of strong growth and high demand for aircraft nor can we give any assurance that following a recession aircraft values and lease rentals will return to Base Case levels. Because actual experience will likely differ from those assumptions, the actual maturities and weighted average lives of the 1998 Notes will likely differ from what is shown in the tables below.

If our lease rentals were to vary as shown below and all of the other assumptions were to prove correct, then the yield to maturity for the subclass C-1 and D-1 notes would be as shown below. If lease rentals significantly declined, there might not be sufficient revenues available to meet interest and principal payments on the 1998 Notes. In such cases, interest on the 1998 Notes would be deferred.
